The notebook will render here: Markdown, code with its In [ ] prompts, tables, charts, printed output and tracebacks, exactly as they were saved.

About IPYNB Viewer

An IPYNB viewer opens Jupyter Notebook (.ipynb) files in your browser and renders them the way Jupyter does: Markdown, code with execution counts, pandas tables, charts, printed output and error tracebacks. Use it to read a notebook from a teammate, a Kaggle download or an email attachment without installing Jupyter or uploading it to Colab, then export it as a Python script or Markdown.

Key Features

Renders Markdown cells (GitHub-flavored, including embedded attachment images) and code cells with their In and Out prompts
Shows the outputs notebooks save: pandas DataFrame tables, PNG, JPEG and SVG charts, printed text and colored tracebacks
Exports a Python script identical to jupyter nbconvert --to python, with %magic and !shell lines rewritten as get_ipython() calls
Exports Markdown with charts embedded as images, ready for a README, a wiki page or a blog draft
Reads nbformat 4 and older nbformat 3 files from Jupyter, JupyterLab, VS Code, Google Colab and Kaggle
Sanitizes HTML outputs and never runs notebook JavaScript, so an untrusted notebook cannot execute code in your browser

Use Cases

Read a notebook a teammate shared in Slack or by email without starting a Jupyter server
Review a data science take-home assignment on a laptop with no Python installed
Convert ipynb to py to move notebook code into a script, a cron job or a pull request
Turn an analysis notebook into Markdown for a README or a Confluence page
Check what a notebook downloaded from Kaggle or GitHub does before you run it

Supported Formats

.ipynb (nbformat 4.x)

.ipynb (nbformat 3)

How do I open an IPYNB file without Jupyter?

An .ipynb file is a JSON document that stores each cell's source together with the outputs saved the last time it ran, so you can read it without a Python kernel. Drop it on this page and the cells render as they would in JupyterLab, with tables, charts and tracebacks intact. Nothing is executed: a notebook saved without outputs shows its code only, interactive widgets need a live kernel, and LaTeX math in Markdown appears as source text. To run the notebook, open it in JupyterLab, VS Code or Google Colab. To keep the code, export it as a .py file.

Privacy & Security

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
